    • An electronic device includes a processor, an internal memory for storing system information and installing programs, and a memory expansion interface for connecting an expansion memory. The expansion memory is partitioned into at least one region to expand the internal memory. The internal memory is partitioned into a system region and a user region; the system region is used to store system information while the user region can be controlled and used by a user. The processor further includes a detection unit and a memory management unit. The detection unit detects the connection of the expansion memory to the memory expansion interface, and the memory management unit determines whether the expansion memory has been previously configured to expand the internal memory, and if not, the memory management unit associates the expansion memory with the internal memory to expand the internal memory.
    • 电子设备包括处理器,用于存储系统信息的内部存储器和安装程序,以及用于连接扩展存储器的存储器扩展接口。 扩展存储器被分割成至少一个区域以扩展内部存储器。 内部存储器被划分为系统区域和用户区域; 系统区域用于存储系统信息,而用户区域可以由用户控制和使用。 处理器还包括检测单元和存储器管理单元。 检测单元检测扩展存储器与存储器扩展接口的连接,并且存储器管理单元确定扩展存储器是否已经被预先配置为扩展内部存储器,如果不是扩展存储器,则存储器管理单元将扩展存储器与 内部存储器来扩展内部存储器。
